I bought this frame a few months ago when they were On offer for £150 with seat pin and headset. Just took it out of the box to build it last week using various parts i had in the garage. Using the Specs from PX website i see it requires a boost crankset (53.4mm) and a maximum of a 32T cog. I have used an old XT crankset and a 36T chainring and it all seems to be working fine. Is there a reason why a bigger than 32T chainring should not be used? And why should a regular crankset not work, given that the chain line is perfect at the recommended spacing? Maybe I’m missing something?
